Backtesting vs paper trading: what each can tell you
Backtesting applies a strategy's rules to historical market data. Paper trading lets you practise with play money as new market data arrives. A backtest can replay years of available history; later practice unfolds day by day. Neither tells you what your future returns will be.
TickerTown is a trading simulation game that uses real market data and play money. It combines historical testing with daily practice, without requiring you to write code.
The difference at a glance
Paper trading varies between tools. Some broker practice accounts let you place orders during the trading day. TickerTown follows daily strategy rules, rather than providing a real-time broker terminal.
| Question | Backtesting in TickerTown | Daily paper trading in TickerTown |
|---|---|---|
| What data does it use? | Available historical market data. | New daily market data as it arrives. |
| How fast does it move? | It replays the historical period shown in the result. | It follows actual trading days. |
| What can you learn? | How the supported rules behaved during that period. | How those rules behave as later market conditions unfold. |
| What can it establish? | A simulated outcome under the test's data and assumptions. | A record of simulated daily decisions and holdings. Neither mode establishes future profitability. |
A historical test answers a question about the past
A backtest asks what would have happened if the supported rules had operated over the recorded period.
That can help you understand what the rules do, when holdings change and how the simulated account changes along the way. A result is more useful when you can explain it than when you only look at its final return.
Read the dates on the result. TickerTown normally requests up to five years of history, but available data and indicator warm-up can shorten the period or prevent a test. Predefined strategies can use saved backtest reports, so selecting one does not establish that its report was calculated today.
A good historical result still describes a selected period. It does not establish that the same outcome will happen again.
Daily practice follows the days that come next
Imagine a supported rule decides to change its holdings after the market closes.
In a backtest, the simulation evaluates that decision against stored data and models the order at a later trading open. In daily practice, it waits for new daily market data before evaluating the rule and processing the resulting simulated orders.
TickerTown's daily practice therefore takes time. It is a place to observe your supported rules as conditions unfold, with play money. It does not offer instant intraday order execution.
How TickerTown uses both
You choose a predefined strategy or supported custom-stock settings, inspect the historical test, then start daily simulated practice. The available controls are specific to those supported strategies. You do not write arbitrary strategy code or place real-money trades.
The historical test helps explain the rules before you use them. Daily practice gives you a later record to inspect. A passing or promising backtest is not a certificate that you are ready to trade real money.
Both modes depend on their data and software. They can contain errors and do not reproduce every brokerage cost, execution constraint or experience of risking real money. TickerTown is an educational simulation, and simulated results do not predict future returns.
